AFR control

[sylvio]

Anything I do , do not work to control my mixture at idle , it always get to 12hight ,13 low after warmup
I change VE # and injectors size, it always go back to 12-13
Its a 3 bars setup with 95pounds injectors lsx 427

Maybe I forgot something in start tune ,

Thanks

Go to Fuel>transient Fuel Qualifications>Min Fuel Milligrams and halve that field.

Any luck

[sylvio]

Yes , its better , but still don't have complete control.i did halve the Min Fuel Milligrams , and get to 13.5 and cut again and get to 13.8
When I use the fuel trim in VCM controller , I need to get to 13 minus to get to 14.7
I didn't have much time to play with that today, I will do tomorrow on dyno.

Thanks to Russ Kemp for your help ,

Your IFR table is set up for a vacuum referenced fuel regulator, but you offset table isn't. Copy your 0 vacuum kpa column and paste it into every column to the right of it.

Any chance you have a cam sensor code?

Don't have cam sensor code .
